SPECIFICATION forming part of Letters Patent No. 523,664, dated July 31, 1 894.

i Application filed December 11,1893. Serial No. 493,296. (No model.)

To all whom it may concern.:`

Beit known that I, GEORGE L. HOOPER, a citizen of the United States, residing in the city of Denver, in the county of Arapahoe and State Of Colorado, have invented certain new and useful Improvements in Ore-Samplers; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and mounted upon or secured to any suitable support. This casing isv provided with lugs or for a shaft B.

O is apulley mounted on shaft B. The pulf ley is preferably provided with a rgrooved flange c'for the convenient attachment of segmental cam blocks el.

D is a section of a spout made of hopper shape and suspended in the casing A, the upper end embracing the spout or hopper in the vcover A. The spout section is provided with trunnion-like projections b b which rest in bearings in the casing. On one of these trunnions is mounted a crank arm or lever h carrying at its free end an antifriction roller 7c.

H is a divider or partition to keep the main` body of the ore and the sample separate.

In operation, Ore is discharged in a continuous stream through the spout or hopper in the -I claim iscover A through suspended hopper-shaped spout section D to suitable ore bin below. Simultaneously with this operationfthe pulA ley C is driven in the direction of` the arrow andthe cam-block d comesin range of the roller 7c on crank-arm hand swings the lower end of the suspended spout section D to the left of divider I-I and discharges a sample of the ore into the bin below. Any number of cam-blocks may be used so as to take a sample from the mainstream one or more times during each revolution of the pulley. The blocks are attached to the pulley by bolts or other convenient means forready attachment and removal, it being understood that the machine is adjustable to take large or small samples, as occasion may require. l

Having now described my invention, what to discharge a sample of its contents outside the main body, substantially as described.

2. In a sampler, the combination of a pendent spout section and a rotary crank arm connected with said section, a cam to engage the end of thel crank arm and vibrate the spout section, substantially as described.

3. In a sampler, the combination of a suspended spout section, a crank-arm connected 4with said section, a pulley provided with grooved iange and cam blocks adj ustably connected with the grooved flange, substantially as described.

Intestimony whereof I aftix my signature in the presence ot' two witnesses.

GEO. L. HOOPER.
